Introduce a new serialport tool: comNG

[xenkuo]

As serialport tool is often needed when develop esp serial chips, and I found there's no such a good software can meet my simple request, I made this one.
Key features include:

built-in comNGLang syntax
built-in word highlighter
globally highlight word you selected (monaco built-in)
globally highlight word you searched (monaco built-in)
breakpoint on certain text
timestamp append and name sign

comNG is commercial software but offer a friendly license to personal and educational projects.
